Pyruvate Dehydrogenase Kinase 4 [PDF]
OBJECTIVE—Pyruvate dehydrogenase complex (PDC) serves as the metabolic switch between glucose and fatty acid utilization. PDC activity is inhibited by PDC kinase (PDK). PDC shares the same substrate, i.e., pyruvate, as glyceroneogenesis, a pathway controlling fatty acid release from white adipose tissue (WAT).

Variation in the organization and subunit composition of the mammalian pyruvate dehydrogenase complex E2/E3BP core assembly [PDF]
Crucial to glucose homoeostasis in humans, the hPDC (human pyruvate dehydrogenase complex) is a massive molecular machine comprising multiple copies of three distinct enzymes (E1–E3) and an accessory subunit, E3BP (E3-binding protein). Its icosahedral E2/

Hyperpolarized NMR study of the impact of pyruvate dehydrogenase kinase inhibition on the pyruvate dehydrogenase and TCA flux in type 2 diabetic rat muscle [PDF]
The role of pyruvate dehydrogenase in mediating lipid-induced insulin resistance stands as a central question in the pathogenesis of type 2 diabetes mellitus.

The mitochondrial pyruvate dehydrogenase complex is regulated by reversible seryl-phosphorylation of the E1α subunit by a dedicated, intrinsic kinase. The phospho-complex is reactivated when dephosphorylated by an intrinsic PP2C-type protein phosphatase.

Metabolic checkpoint of ferroptosis resistance
The metabolic checkpoint of ferroptosis remains obscure. We find that glucose favors system xc− inhibitor-induced ferroptosis by activating pyruvate oxidation, thereby promoting fatty acid synthesis and subsequent lipid peroxidation.

Metabolic responses of primary and transformed cells to intracellular Listeria monocytogenes. [PDF]
The metabolic response of host cells, in particular of primary mammalian cells, to bacterial infections is poorly understood. Here, we compare the carbon metabolism of primary mouse macrophages and of established J774A.1 cells upon Listeria monocytogenes

Regulation of heart muscle pyruvate dehydrogenase kinase [PDF]
1. The activity of pig heart pyruvate dehydrogenase kinase was assayed by the incorporation of [32P]phosphate from [γ-32P]ATP into the dehydrogenase complex. There was a very close correlation between this incorporation and the loss of pyruvate dehydrogenase activity with all preparations studied. 2.

Allosteric Coupling in Pyruvate Dehydrogenase Kinase 2 [PDF]
Mitochondrial pyruvate dehydrogenase kinase 2 (PDHK2) phosphorylates the pyruvate dehydrogenase multienzyme complex (PDC) and thereby controls the rate of oxidative decarboxylation of pyruvate. The activity of PDHK2 is regulated by a variety of metabolites such as pyruvate, NAD (+), NADH, CoA, and acetyl-CoA.

Chemotherapy-induced painful peripheral neuropathy (CIPN) is the most common toxicity associated with widely used chemotherapeutics. CIPN is the major cause of dose reduction or discontinuation of otherwise life-saving treatment.

Summary: Although induction of ferroptosis, an iron-dependent form of non-apoptotic cell death, has emerged as an anticancer strategy, the metabolic basis of ferroptotic death remains poorly elucidated.
